摘要： A communication method and a communications apparatus are provided. The method includes: sending, by a network device, indication information to a terminal, where the indication information is used to indicate at least one second BP associated with a first BP; and performing signal transmission, by the network device, with the terminal on the first BP and the at least one second BP. It may be learned that the network device indicates, to the terminal by using the indication information, the at least one second BP associated with the first BP, so that the network device and the terminal can transmit signals on BPs that are associated with each other. In addition, there may be a plurality of second BPs associated with the first BP.

摘要： A communication method and a device are provided, to reduce power consumption of a terminal device and reduce system overheads. A communication method can include, at least, determining, by a terminal device, that a plurality of BPs are activated, where the plurality of BPs are in a same carrier, the plurality of BPs include a first BP and a second BP, a first CSS is configured in the first BP, and common DCI is configured in the first CSS. The communication method can further include detecting, by the terminal device, the common DCI only in a second CSS when the second CSS is configured in the second BP, where the common DCI is configured in the second CSS.

摘要： A method includes: communicating, by a base station, first UE specific information of UE with the UE in a UE source operating bandwidth resource; and sending, by the base station, information about a UE target operating bandwidth resource of the UE to the UE in a UE calibration bandwidth resource of the UE, where the UE target operating bandwidth resource is used by the base station to communicate second UE specific information of the UE with the UE, and the UE source operating bandwidth resource is not completely the same as the UE calibration bandwidth resource.

摘要： A resource indication method, a device, and a system relate to the field of communications technologies. The method includes: allocating, by a base station, a BP to a terminal device, and sending, to the terminal device, a first message indicating a resource position of the BP; and receiving, by the terminal device, the first message sent by the base station, and then determining the resource position of the BP based on resource position information of at least one sub-BP, where the BP includes the at least one sub-BP, the BP is not greater than a maximum bandwidth supported by the terminal device, and the first message includes the resource position information of the at least one sub-BP. The BP is allocated by using a sub-BP as a granularity, so that signaling overheads can be reduced while a requirement for more flexible resource allocation is satisfied.

摘要： A power control method and apparatus that relates to the field of communications technologies. The method includes: determining, according to a power offset parameter configured by a network side, a first power offset value used by a control channel corresponding to a first subframe, and determining a second power offset value used by a control channel corresponding to a second subframe; feeding back the control channel corresponding to the first subframe to the network side by using the first power offset value; and feeding back the control channel corresponding to the second subframe to the network side by using the second power offset value. The power control method and apparatus are applicable to a multiflow transmission scenario in which a UE feeds back control information to a network side.

摘要： A method for determining time information is disclosed. The method includes: obtaining, by a network node, information sent by a terminal device; and determining, by the network node, at least one of the following based on the information: a first time interval between downlink scheduling and downlink data transmission, a second time interval between the downlink data transmission and a feedback message sent by the terminal device after the terminal device receives downlink data, and a third time interval between uplink scheduling and uplink data transmission, where the information may include at least one of a subcarrier spacing, an operating band, and a bandwidth that are supported by the terminal device, and further include a first smallest value and/or a second smallest value and/or a third smallest value corresponding to the at least one item. Therefore, flexibility and accuracy of determining the time information are improved.

摘要： A timing advance determining method and a device are provided. In the method, a network device determines, based on a correspondence between a parameter set and a TA granularity, TA information used by a terminal on an occupied frequency domain resource, where the parameter set includes a subcarrier spacing and a cyclic prefix type of a symbol; the network device sends the TA information to the terminal; and the terminal determines, based on the correspondence between a parameter set and a TA granularity, a TA granularity corresponding to the frequency domain resource occupied by the terminal, and determines, based on the TA granularity and the TA information, a TA value used by the terminal on the occupied frequency domain resource.

摘要： Example transmit devices, receive devices, and related methods are described herein, In one example, transmission burst information is provided to a receive device by downlink control signalling. An example transmit device is configured to transmit a Downlink Control Information, or DCI, the DCI including the transmission burst information. The DCI has the same number of bits as a DCI format used for PDSCH scheduling.
